CONVEYER FOR TAMPING MATERIALS.

SPECIFICATION forming part of Letters Patent No. 542,151, dated July 2,1895.

Application filed November 1, 1894. Serial No. 527. 81- (No model.)

To all whom it may concern:

Be it k nown that we, ROBERT H. ELLIOTT and J OHN B. CARRINGTON,citizens of the United States, residing at Birmingham, in the county ofJefferson and State of Alabama, have invented certain new and usefulImprovements in Conveyers forTamping Material; and we do hereby declarethe following to be afull, clear, and exact description of theinvention, such as will enableothers skilled in the art to which itappertains to make and use the same.

Our invention relates to improvements in appliances for insertingtamping material in drill-holes, and consists of certain novel featureshereinafter described and claimed.

Referenceis had tothe accompanyingdrawings, in which the same parts areindicated by the same letters throughout the several views.

Figure 1 represents a side elevation of the device ready for insertingin the drill-hole. Fig. 2 represents an end view as seen from the leftof Fig. l and on an enlarged scale. Fig. 3 represents a side elevationshowing one of the sliding parts of the tamping appliance drawn partlybackward.

The appliance consists of two interlocking semicylinders A and B,connected together by the hooks (b and 5, formed from the turnedoveredges of the said semicylinders, as shown in Fig. 2, and the said twoparts are free to slide longitudinally relative to each other, yet

when hooked together, as shown, constitute a complete tube or cylinderadapted to contain the tamping material.

Each of the sliding pieces A and B is provided with a handle 0.

The operation of the device is as follows: The two semicylinders areinterlocked, as shown in Fig. 1, by sliding the one within the other.The end of the completed tube is stopped up with a wad of paper, cottonwaste, or other suitable material. The tube is filled with the tampingmaterial. A second Wad is inserted 5 in the opposite end of the tube, ifdesired, and

then the tube is inserted in the drill-hole to the required depth. Oncein the hole at the proper depth the upper half of the tube is slid out,leaving the tamping material resting in thelowerhalf of the tube andpartly overflowing the edges thereof. Then the bottom piece is twistedaround through one hundred and eighty degrees by means of its handle,and it can be readily pulled out without dragging out with it anyappreciable amount of tamping material. In this way the tamping materialmay be placed at any desired portion of the drill-hole. It may then berammed with the ordinary rainmer or the hole maybe closed in theordinary way.

IVe do not mean to limit ourselves to any particular form oflongitudinally divided tube, nor is it necessary to make the two partseach semicylinders or of equal size, although this construction ispreferred.

The various advantages of the herein-described appliance will be readilyunderstood by any one skilled in the art.

Having thus described our invention, what we claim, and desire to secureby Letters Patent of the United States, is

1. A conveyer for tamping material, consisting essentially of twosuperimposed hollow semicylinders the one being adapted to slidelongitudinally relatively to the other with guides for holding the twosemicylinders together, and means for separately holding and moving thesemi-cylinders substantially as and. for the purposes described.

2. A conveyer for tamping material, consisting of two superimposedhollow semicylinders having their longitudinal edges bent so as to hooktogether, and yet leaving the two parts free to slide longitudinally,with a handle attached to the inner end of. each of said semi-cylinders,substantially as and for the purposes described.

In testimony whereof we affix our signatures in presence of twowitnesses.
